completed and the instrument indicates the results automatically through Window No.01.
Repeat zero set calibration if it still needs to be minimized, i.e. the velocity reading is still
high.
3.12 HOW TO GET A SCALE FACTOR FOR CALIBRATION
The scale factor is the ratio between the ‘actual flow rate’ and the indicated value by the flow
meter.
The scale factor can be determined by calibration with flow calibration equipment.
3.13 HOW TO USE THE OPERATION LOCKER
The system locker provides a means of preventing inadvertent configuration changes or
totalizer resets.
When the system is locked, menu window browsing can be done without affecting any change,
but any modifications are prohibited.
The system can be locked without a password or with a one 1 to 4 digit password. With a
no-password locking, directly press the ENT key when the password input prompt displays.
If the password is forgotten, please contact the factory.
3.14 HOW TO USE THE BUILT-IN DATA MEMORY
The data memory has a space of 24K bytes of memory, which will hold about 2000 lines of
data.
Use M50 to turn on the data memory and for the selection for the items that is going to be
logged.
Use M51 for the times when the logging begins and at how long an interval sustains and how
long the data logging will last.
Use M52 for the direction of logging data. The default setting will permit the logging data to
be stored in the data memory buffer.
Logging data can be redirected to the RS-232C interface without being stored into the data
memory buffer. Dumping the logging data through the RS-232C interface and the clearing of
the buffer can be operated with a function in window M52.
Use M53 to view the data in the data memory buffer.
3.15 HOW TO USE THE FREQUENCY OUTPUT
Only For Flow Rate Output.
There is a Frequency Output in all series TF1100 flow meters. This frequency output signal,
